Conductor Plugin

Measure twice, code once.

Conductor is a plugin for AI coding agents (including Antigravity and Claude
Code) that enables Spec-Driven Development. It turns your agent into a
proactive project manager that follows a strict protocol to specify, plan, and
implement software features and bug fixes.

Instead of just writing code, Conductor ensures a consistent, high-quality
lifecycle for every task: Context -> Spec & Plan -> Implement.

The philosophy behind Conductor is simple: control your code. By treating
context as a managed artifact alongside your code, you transform your repository
into a single source of truth that drives every agent interaction with deep,
persistent project awareness.
